题目内容

A drug used to treat severe bleeding could save thousands of lives for mothers giving birth. A global trial of the drug found it reduced the risk of bleeding deaths during childbirth by nearly one-third. The study involved 20,000 women in 21 countries, mainly in Africa and Asia. The trial was carried out by London's School of Hygiene and Tropical Medicine. The drug is called d tranexamic acid （氨甲环酸）. It is low-cost and researchers said it does not cause serious side effects for mothers or babies.

The drug is used to treat mothers for severe bleeding during childbirth, also known as postpartum hemorrhage (产后出血).It is the leading cause of mother’s death worldwide, according to the World Health Organization.

Haleema Shakur is the project director of the trial. She says despite medical advances in many countries, severe bleeding after childbirth remains a big problem in some parts of the world. “It's one of the biggest killers of mothers. In Africa and Asia. about 10 percent of women will end up with severe bleeding. " The drug works by stopping blood clots（血凝块） from breaking down after a mother gives birth. The treatment can prevent the need for doctors to perform surgery to find the source of bleeding.

Shakur said the best results were reported when the drug was given to women as soon as possible after childbirth, “The earlier you give it- so within the first three hours of giving birth—the better the effect is. ”

The next step will be to get the drug where it is needed provide training for doctors and nurses on how to use it. During the trial, women were given the drug in a hospital. But researchers are looking for easier ways to administer the drug so it can be more widely used in small clinics and rural areas.
